The STS-spiral roller brush range from Obtuz contains all measurements from small to extra large and this unbeatable selection of diameters makes this brush a totally reliable tool for light brushing tasks. Due to the high fill density and precisely ground surface it achieves outstanding results. A flawless radial true runing is a requirement in most cases to achieve the desired brush effect. Therefore the brush cores are electrodynamically pre-balanced and re-balanced according to the required RPM after assembly of the spiral brushes. The balancing quality refers to quality grade G 2.5 as per ISO 1940.
Fixing of the spiral coils
The coils are generally mounted onto the roller cores with pressure rings (PRB) in order to prevent the brush from roating on the core. Depending on the work and the rotation speed of the brush the coils can also be spot-welded or screwed onto the core.
Surface speed
You can use our spiral roller brushes up to a surface speed of 30 m/sec. maximum without problems.
